Thread: Odd question

dont know that anyone has tried it to tell if the knock sensors pick it up at all. if youre willing to give it a shot then more power to ya, but i really dont get why people dont trust the double rollers. mine has been in my car for 20k+ miles already.

Between chain quality issues and the crank gears not being chamfered right, I wouldn't trust one either.

Knock sensors are just little microphones. The PCM is programmed to pick up a particular frequency which coincides with predetonation. Unfortunately anything making excessive noise that partially covers that frequency will also be picked up.
